A. H. MmGLEY. PERCUSSION FUSE FOR EXPLOSIVE PROJECTILES. .APPLICATIONFILED MAY 23. I9I7`.

sigisiijj To dll whom t mag/concern: I i' Be it .known that I, AIBERTHENRY MIDG- LEY,a-subject of fthe King of Great Britain and Ireland,andresiding at Warple Way, v.Acton Vale, in; the county of Middlesex, fEngland, have invented certain new and useful Improvements in andRelating to Pery cussion-,Fuses for Explosive Projectiles, of 1 whichthefollowin'g is a specification.

.1This;invention,relates to percussion fuses for explosive: projectilesand more particularly. for projectiles intended to lbe used. with l 3asmooth bore gun, such as a Stokes gun of the :kind-infwhich thestriker'andthe cap gar'ecarried by two separate blocks capable'of:axial,movement relatively to eachother :and 'are keptA in an.inoperative Vposition Y by f a spring anda suitable member interposedfbetween the twoblock's. Y

1 It'has previously been proposed in a perv-cussiony fuse-fin which thetwo pellets the blocks ecarrying'; the striker and the cap 1Yrespectivelyy are'V capable of axial movement relatively toeach other,to keep the blocks finianinoperative vposition by a safety memt berinterposed directly between the striker the percussion cap, said safetymember ybein'gkept in-its safety position by means Vprovided insidethefuse holder and being `rOtated therein by said lmeans when the pro,-V.fjectile'is-ired morder to remove the Sportionof the safety memberlying directly b'etween -the` striker and the percussion fcap fromsuchposition; Y

' The invention consistsfin arranging' the V4safety memberin apercussion fuse of the Y'kind ir'stiabove referred to, in suchapositinasto-.bei directly-interposed between the striker and the capand retaining it in its j inthe arrangement according to the presentinvention the rotation of the shell within the gun is not dependeduponfor the removal of the safety member, such removal taking place-duringthe -flight of the shell through ytheair. The-invention also consists inthe provif sion of means for preventing the'fuse being assembledunlessthel safety member lies directly betweenthe percussion .cap and thestriker, such means preferably consisting Qin the provision of a ridgeand corresponding Vdepression on the two blocks respecv Specification ofLetters Patent i ,safetyposition by .means provided outside; the` fuseholder.

The invention is illustrated by wayof ex-l .ample fin the accompanyingdrawings in which,

Figures 1 and 2 are two sectional eleva- `tions at right angles to eachother, and

Fig. 3 is a sectional plan of the im.
